I don't have a high resolution one for the Electronic Injection Circuit for this Vehicle, sorry. I can only provide a poor image on this occasion, but you can magnify it up slightly by clicking the image.

Thank you, I will try to zoom in. I need to find the supply connections and to follow their route.

Hi there,
Maybe you can help me on how this was finally fixed.
I own a DS5 Hybrid 2012 and I have similar issue with my DS5.
I had an DPF error, that I had solved, but after few days and a railway cross, another few errors appeared.
My error codes are:
P0103 - Air flow signal, high - Intermittent
P0102 - Air flow signal, low - Intermittent
P0113 - Intake air temperature signal (air flow sensor) - Short circuit to positive or open circuit - Intermittent
D288 - Unknown fault code
P0215 - Principal relay. Poor operation of the relay, the ECU is not being supplied as it should be - Intermittent
P0299 - charge pressure regulation - Air pressure lower than reference value - Intermittent
I tried to reset the codes but the system wouldn't allow me.
The car is running fine, but I still wanted to have it fixed so I left it with the mechanic that has a licensed diagnose for PSA.
Unfortunately he was not able to reset the codes eider.
What can I do?
